Introduction to Linux - A Hands on Guide

This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

The Dapper screen pref gui default res is 1280 x 1024. This looks most appropriate and i can't alter it to lower resolution in the dropdown. The same applet claims my refresh rate is 86 Hz and likewise i cannot change it, -but my screen looks like 60 Hz, which is the reading my monitor displays when i press a button on the cabinet. This is too low and it trails smears when i move windows.

I can lower the the resolution by deleting the 1st settings ( 1280 x 1024 ) from each modes line in the /etc/X11/xorg.conf but i'm sure these are less appropriate settings. Here is the relevant sections from my /etc/X11/xorg.conf

How old is your computer? Mode lines are practically extinct, and refresh rates can usually be guessed correctly by the X server on its own with modern monitors, and to top it all off, your using the vesa driver, which signifies that you either don't care about your hardware or their isn't any better drivers, or your really using OLD hardware, so what is it?

Options: Did someone suggest i could alter my position with a driver other than my Vesa ?

Hi nnjond

Apologies, I'm not very busy on forums.

If you know what a terminal is, type "sudo dpkg-reconfigure xserver-xorg"

Choose your graphics card/adapter from the list, follow the text, if there's anything you don't understand press "esc" (this will skip). When you come to resolution, enter 1600x1200 with the space-bar. Choose "medium" for the settings, move down to 1600x1200@75Hz.

This will give you a range of resoloutions between 1600x1200 and 648x480.

Thanks for the tip. It made perfect sense. All seemed to go perfectly well. However when i restarted, the user and password screens appeared, so i tapped in my details... It halts on a black page of text before returning to the user and password screen. There dosen't seem to be a way in?

That sounds like you have the wrong password or user name? As you seem to have had these problems for some time, I would suggest doing a fresh install with whatever version of Ubuntu you are using. Best I can do! :-)
